BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 498,642, dated 'May 30,1893. i

Application filed August 30, 1892-V Serial No. 444,586. (No model) i Toa/ZZ whoml t may concern: I

Be it known that I, ROBERT GARRET, residing at Freedom, in the county ofBeaver and State of Pennsylvania, have invented certain new and usefulImprovements in Brick-Kilns, of which the following is a specication.

My invention relates to brick kilns in which a combined up and downdraft isemployed, and it has for its object to provide a `kiln of thischaracter simple in its construction, in which the heat products arethoroughly disseminated among the ware in such manner as to quickly andevenly burn it at all parts of the kiln.

lVith other objects inview, all of which will hereinafter be fully setforth, my in vention consists in the peculiar combination andlnovelarrangement of parts, all of which will hereinafter be fullydescribed in the specification andparticularlypointedout in the claims,reference being had to the accompanying drawings, in which- Figure l isla horizontal section of my improved brick kiln on the lines l-l 2-2 3 3and 4 4 Fig. 2. Fig. 2 is alongitudinal sectionthereof on the line 2 2Fig. l and Figs. 3 and 4 are detail views hereinafter more particularlyreferred to.

Referring to the accompanying drawingsl-il indicates the kiln bodywhichis preferably circular in shape as shown, although in someinstances it may be desirable tomake it square or other shape; and-Bindicates the ioor, which is practically a solid one it being formed ofbricks laid alternately on their flat sides and on edge, with an inch ofdirt between themto make the floor air tight.

Beneath the ioor are arranged four independent flue sections C, each ofwhich is formed with a series of bridge walls c, spaced apart,"whereby aseries of heat chambers c', are formed to thoroughly spread the heatunder the door. Each flue section C is connected with a furnace D, andsuch sections communicate with a series of short vertical flues E, whichopen up through the floor B and discharge into the interior of the kiln.

Below the door Iiues C are arranged the main draft ues F which extendunder the kiln floor at right angles to each other, and are connected attheir outer ends withthe stacks G. These [lues F communicate with thekiln chamber through a series of down draft openings H which extendAfrom such dues up through the kiln floor. Each of the draft lues F ishorizontally divided as at F whereby lower damp air chambers ll2 areformed, with which lthe door lines communicate, through the fluesections l. such chamber being formed by setting the bricks alter-.nately endwise and flat with `dirt between them to render the divisionwall practically By this construction-I am enabled itas it were, in asemi dry state, before the furnaces are started. It will thus be seenthat theware at the bottom will thereby retain its original shape, andbeing in a partially dry state will thereby burn more uniform in a lesstime and with a much less fuel consumption than in the ordinary way.

The construction so far described, provides for an up draft burn, tocombine with it an additional up draft, or a combined up and down draft,I employ the means most clearly shown in Fig. 2 of the drawings, suchmeans consisting of four furnaces J arranged intermediate the furnaces Dbut at a point above the kiln floor such furnaces discharging intopockets or fire chambers K projected into the interior of the kilnchamber and open at the top as shown. y

With each of the furnaces communicates a iiue or channelway L formed inthe side walls of the kiln, (see Figs. 2 and 4) which have dampers Znear their upper ends and which extend down and communicate with doorlines, fed from the lower furnaces D. It will be noticed that by closingthe dampers in the dues L the fire-from the furnaces J will bedischarged into the pockets K, pass over the tops thereof, enter theware and be drawn down to comminglewith the up draft heat and IOO passoff with it through the down draft flues in the floor, into the stacklines. It' desired the dampers Z may be opened and a part of the heat ofthe furnaces J will be deliected and carried into the floor fines.

By arranging a number of furnaces .leach with independent lire pocketsat its rear end, and a number of door flue sections with an independentfurnaceD for each, the re in the several furnaces D and J can be soregulated as the condition ofthe Ware at the different portions of thekiln may Warrant.

The kiln chamber dome is formed with the usual cooling outletsin its topand the stacks with the usual dainpers. v

Y Having thus described my invention, whatI claim, and desire to secureby Letters Patent, ls-

1. A brick kiln having a series of hot air chambers under the floor, andhaving branch outlets opening into the kiln chamber, stack lilies havingbranch lues opening through such kiln floor, furnaces discharging intothe hot air chambers7 openings in the kiln Wall above the floor, asecond set of furnaces dis'- charging into the aforesaid openings in thekiln Wall, and Valved Iiues connecting such openings and the hot airchambers under the kiln floor, all arranged substantially as shown anddescribed, whereby a combined up and down draft is obtained and wherebya p0rtion of the heat products of the upper furnaces can be deflected todischarge into the hot air chambers under the floor to pass out with theup draft, as set forth.

2. In a brick kiln having a down draft, the combination With the stackand the kiln chamber, of stack fines having damp air compartmentscommunicating with kiln chamber and opening into the stack substantiallyas and for the purpose described.

3. A brick kiln having a non slatted floor section, a seriesofindependent hot air chambers under such floor having discharge tluesopening into the kiln chamber, furnaces for each of such hot-airchambers, the stacks, the stack fines having flue sections opening intothe kiln chamber, said stack flues each formed with a damp aircompartment openinginto the stack and flue ways connecting the hot airchambers with the damp air compartments substantially as and for thepurpose described.`

4C. An improved brick kiln having its iioor provided with dischargelines, the stack ues under such door, with which such discharge finesconnect, said stack flues having damp air compartments, a series of hotair chambers under the fioor having fines opening up through such tloor,the furnaces D, discharging into' the said hot airchambers, a series ofvpockets K openat their top in the kiln cham-V ber a series of furnaces Jdischarging into such pockets the Valved flues L connecting the furnacesJ'and the hot airchambers and the iiues I connecting such hot airchambers with the damp air compartments in the stack fines all arrangedsubstantially as shown and for the purposes described.
